在标题化合物C25 H23 NO 4中，吡咯嗪环近似为平面，与平面度的r.m.s偏差为0.0053 μ m，而稠合的二氢吡咯嗪环则呈信封构象，C原子连接到两个CH 2上作为翼片。 稠环系统与苯基和甲基苯甲酰基环之间的二面角分别为41.65（11）°和66.30（8）°。 晶体中存在较弱的C-H <$O氢键和C-H <$π相互作用。一个分子通过八个氢键与五个相邻的分子连接，形成三维网络。
In the title compound, C25H23NO4, the pyrrolizine ring is approximately planar with an r.m.s deviation from planarity of 0.0053 Å, while the fused dihydropyrrolizine ring adopts an envelope conformation with the C atom connected to two CH2 as the flap. The dihedral angles between the fused ring system and the phenyl and methylbenzoyl rings are 41.65 (11) and 66.30 (8)°, respectively. In the crystal, weak C—H⋯O hydrogen bonds and C—H⋯π interactions occur. One molecule is linked to five adjacent ones through eight hydrogen bonds, forming a three-dimensional network.
